Embodiment Construction

[0014] figure 1 It is a schematic diagram of the configuration of the fan-shaped long bar magnet with the N pole at the upper end and the S pole at the lower end and the two bar magnets on the magnet in different magnetic pole directions. Of course, the long fan-shaped bar magnet of the present invention can also have an S pole at the upper end and an N pole at the lower end. pole.

[0015] to combine figure 1 The self-rotating bearing with magnets of the present invention includes an inner ring 1, a rolling element 3, a cage 2 and an outer ring 4, and the rolling element 3 is installed between the inner ring 1 and the outer ring 4 through the cage 2. This bearing structure is one of the most common structures in the art. The cage 2 can be designed into different structural types according to different working conditions. Both the inner ring 1 and the outer ring 4 are made of non-magnetic or weak magnetic materials, such as 25Cr18Ni10WN, 7Mn15Cr2Al3V2Wmo or ceramics. Both ...

Abstract

A self-rotating bearing with magnets includes an inner ring (1), rolling elements (3), a cage (2), and an outer ring (4), and also includes sector-shaped elongated magnets (5) and magnets (6). Sector-shaped strip magnets are equipped in several fan-shaped through grooves that are evenly distributed on the outer diameter end face of the outer ring (4), and the magnetic pole directions of all sector-shaped strip magnets are consistent. The place where the outer ring (4) does not touch its outer diameter end face is symmetrically and evenly distributed with n magnets, and the strip magnets (7) are equipped in the elongated slots on the two hypotenuses of each magnet's protruding head. The poles of the two bar magnets are in opposite directions. The N pole and S pole of each bar magnet attract or repel the fan-shaped long bar magnet to promote the self-rotation of the outer ring. The self-rotation of the outer ring does not consume oil, electricity and fuel, which reduces the operating cost and generates less friction torque. It is small, easy to lubricate and maintain, and is used in textile industry or indoor exhaust fans, etc., where the requirements for rotational torque and speed are not too high.

Description

technical field [0001] The invention belongs to the technical field of bearings, in particular to a self-rotating bearing with magnets. Background technique [0002] Rolling bearings have been widely used in various machines and devices such as transportation vehicles, machine tools, textile machinery, mining machinery, construction machinery, aircraft, ships, robots, precision instruments, and electronic computers. But at present, all rolling bearings must operate under the condition of consuming oil, electricity and fuel, such as driven by electric motors and diesel engines. So far, no self-rotating bearing with magnets has come out. Contents of the invention [0003] The invention provides a self-rotating bearing with a magnet, which can realize its own rotation even without consuming oil, electricity and fuel, so as to achieve energy saving and cost reduction. [0004] In order to realize the foregoing invention object, the present invention adopts following tec...
